Wider weather episode

A short wave trough pushed through central California during the evening of January 6, but skies cleared out and winds diminished behind it as high pressure built back into the area overnight. An area of dense fog formed from Turlock to Delano overnight as a result of clear skies, light winds and inversion conditions over the San Joaquin Valley. The fog dissipated by late morning from Fresno southward and lifted into a low cloud deck north of Fresno which persisted for much of the day.
